Hauv tsab xov xwm no peb yuav paub dab tsi yog IPTV nws yog cov yam ntxwv thiab nws cov txiaj ntsig.
IPTV yog kev sib tham sib tham hauv xov tooj cua, uas yog cov cuab yeej tshiab uas siv broadband cable TV network thiab koom ua ke ntau yam thev naus laus zis xws li Internet, multimedia, thiab kev sib txuas lus los muab cov neeg siv hauv tsev nrog ntau yam kev pabcuam sib tham, suav nrog cov TV digital. Cov neeg siv tuaj yeem txaus siab rau cov kev pabcuam IPTV hauv tsev. IPTV tsis yog tsuas yog txawv ntawm ib txwm analog cable TV, tab sis kuj txawv ntawm classic digital TV, vim hais tias ob qho tib si analog TV thiab classic digital TV muaj cov yam ntxwv ntawm kev faib zaus, sij hawm, thiab ib-txoj kev tshaj tawm. Txawm hais tias classic digital TV muaj ntau yam kev siv thev naus laus zis piv rau analog TV, nws tsuas yog hloov pauv hauv daim ntawv ntawm lub teeb liab, tsis yog txoj hauv kev tshaj tawm cov ntsiab lus.
Nws cov qauv tsim feem ntau suav nrog subsystems xws li streaming media service, program editing, storage, authentication and billing, etc. Cov ntsiab lus tseem ceeb khaws cia thiab xa mus yog streaming media files nrog MPEG-2/4 tus qauv raws li cov tub ntxhais encoding, raws li IP network. kis tau tus mob, feem ntau yuav tsum tau teeb tsa cov ntsiab lus faib cov kev pabcuam nodes, teeb tsa cov kev pabcuam streaming media thiab cov khoom siv khaws cia, thiab cov neeg siv lub davhlau ya nyob twg tuaj yeem yog IP teeb-saum lub thawv + TV, lossis PC. IPTV tuaj yeem siv cov kev tsim kho vaj tse ntawm cable TV network, siv lub TV hauv tsev ua cov khoom siv dav hlau loj, thiab muab ntau yam kev pabcuam digital media suav nrog TV cov kev pabcuam hauv Is Taws Nem raws tu qauv.
Cov yam ntxwv tseem ceeb ntawm IPTV tau tshwm sim hauv plaub yam hauv qab no:
(1) Kev coj tus cwj pwm ntawm IP network, nws tuaj yeem muab cov neeg siv khoom siv cov ntaub ntawv xov xwm zoo tshaj plaws;
(2) Ua kom muaj kev sib raug zoo ntawm cov chaw muab kev tshaj tawm thiab cov neeg siv xov xwm, thiab cov neeg siv tuaj yeem sib tham sib txiav txim siab lawv cov ntsiab lus nyiam;
(3) IPTV tuaj yeem muab cov kev pabcuam hauv lub sijhawm thiab tsis yog lub sijhawm tiag tiag, IP thev naus laus zis thiab kev pabcuam raws li tus kheej xav tau, kom cov neeg siv tuaj yeem tau txais cov kev pabcuam hauv-lub sijhawm thiab tsis yog-lub sijhawm tiag tiag uas muab los ntawm broadband IP network ntawm kev thov;
(4) Cov neeg siv tuaj yeem xaiv cov kev pabcuam video tau muab los ntawm ntau lub vev xaib ntawm broadband IP network.
Cov saum toj no yog "IPTV" kev paub piav qhia coj los ntawm Shenzhen HDV photoelectric Technology Co., Ltd. Cov khoom sib txuas lus tsim los ntawm lub tuam txhab npog:
Module qeb: optical fiber modules, Ethernet modules, optical fiber ntau transceiver modules, optical fiber nkag modules, SSFP optical modules, thiabSFP optical fibers, lwm.
ONUqeb: EPON UA, AC ONU, Optical fiber ntau ONU, CATV UA, GPON UA, XOV TOOJ, lwm.
OLTchav kawm: OLT hloov, GPON OLT, PEB OLT,kev sib txuas lusOLT, lwm.
Cov khoom lag luam module saum toj no tuaj yeem muab kev txhawb nqa rau cov xwm txheej sib txawv. Ib pab neeg R & D muaj zog thiab muaj zog tuaj yeem pab cov neeg siv khoom nrog cov teeb meem kev lag luam, thiab pab pawg ua lag luam muaj kev xav thiab kev ua haujlwm tuaj yeem pab cov neeg siv khoom tau txais kev pabcuam zoo thaum lub sijhawm sib tham ua ntej thiab ua haujlwm tom qab tsim khoom. Zoo siab txais tos koj tiv tauj peb rau txhua yam kev nug.
